insilaring malarial 2L is arranged within ale draw. Similar insulating i'nateriul 21. is also provided between the spaced front and rear walls t thoroughly insulate the :asing. The top oi" the casing thus formed is preferably open and provided with a removable cover 22, whirh may he removably seemed in position in any suitable manner and *he rasing may besi'ippori'ed by means of suitable legs:

The incubator is healed by water circulation, and for that purpose there is provided a, tank of any suitable and convenient The top of the tank 24- .is open as at 27, and the water 18 heated by means of an incandescent lamp 28, the latter being: in-

sorted into ll e \i'ater as shown in Fig. 4:. The lamp is supported by a cover for the (.1 n portion oi the tank and this cover is preferably uonstructml of two elomenls i l), 30 which are held spaced from each other, iio form a rhamher Ill therehetween. The element :15) is; formed with a circumferential seat- 32, adapted to engage the edge ol the open porljion oi the lanlc so that when the cover is placed in position it will he lrietionally held. The element 30 is provided with a stocked 391 for the lamp, while the elen'ionl. 29 provided with an opening 3 1' a1 1': iged in alinoment with the soekei. By dais means, the lamp )8, which nuay he of an ordinary sixteen (lllllllj power, is inserled through tl e opening so that its end will eng a e in he soch'ei' 33, and when iho lamp is screwed in the soekeh'the lamp will engage the wall of the opening 34- and serve to draw the two elemeiits 22). 30 together and hold them against so aration. il ith lhis UUIlSiZlllLtlOH it will he manifest limo-when it is desired to fill the tank all Lhafi is necessary is to remove the cover nd the lamp will he removed with the core llhe chamber between the eleme t? 29,

30, is provided with a series of outlet openings 35, so as to permit any vapor which may be formed along the wall of the lamp and which enters the chamber 31 to escape into the atmosphere, the lamp fitting the opening sufliciently to permit the vapor which may be formed on the lamp to pass from the tank into the chamber 31.

The cover or top of the incubator 22, is so positioned that access may be readily had to the cover of the tank and the lamp with out removing the cover 22.

In order to automatically control the circuit of the lamp, a thermostat is provided, and in the present form of the invention, the thermostat comprises the disks 30 which are supported by a bracket 37 secured to the wall '10 of the incubator. An insulating' post 38 is connected with one of the disks 236 and this post supports a metallic plate or arm 39, having connected with it a binding post 40 to which the conductor 41 is secured. The plate or element 39 Sup ports an adjustable contact point 12, adapted to be adjusted by means of a thumb nut 43. Another contact -11 which cooperates with the contact 13, is supported by a bracket 45 and to the contact =14 is connected a conductor 16 which leads to the lamp 28, while another conductor 16, leads from the line to the lamp. Thus it will be seen that when the contacts 42, 44 are in engagement, the circuit will be completed through the lamp 28 to heat the water in the tank, but when the tenniierature in the incubator rises to expand or adjust the disks 36 suliiciently to separate the contacts 42, 44, the lamp circuit will be broken and the light extinguished. \Vhen the temperature lowers sulliciently the disks 30 will contract and the contacts 42, L-t will be again brought into contact to complete lamp circuit.

In order to thoroughly insulate the contact points 342, 44, and to protect them as ell as the incubator, there is provided an insulating element 47, which is provided with a recess or hollow portion 48 into which the contacts 42, :11 project, and within which portion the contact is made,

With this improved construction it Will be lnanil'est that a light structure will not only result, but it will be absolutely fireproof and with this construction. it is also possible to heat the water sulliciently with a' single sixteen candle power lamp and no fumes, gases or odors will be present, inasmuch as the heating is accomplished by means of hot water circulation.

'lo ventilate the incubator, the end wall lfi is provided with one or more openings 49 adjacent the bottom thereof, which permits outside air to enter the space between the walls 16, 17 and the wall 17 is provided with one or more passages a0 forming communication between the space between the walls and the inside of the incubator, adjacent the top thereof, and also adjacent the water circulation pipe 25. The opposite wall 15 is provided with one or more openings 51 adjacent the bottom thereof, forming connnunication between the interior of the incubator and the space between the walls 11 and 15, while the wall 14 is provided with one or more openings 52 therethrough arranged out of alinement with the openings 51. Thus the air will enter the opening 19, flow through the space between the walls 16, 17 into the incubator and through the openings 50, around the pipe 25 and circulate through the incubator to the opposite side thereof and through the openings 51 into the space between the walls 14, 15 and out of the openings 52, thereby insuring perfect ventilation of-the incubator.

An egg tray 53 is removably supported within the incubator above the bottom thereof so as to form a chamber 5-1 beneath the tray, and the chamber 54 and tray are -ing about the incubator, and an electric vacuum heating element supported by the tank for tree removal and extending into the tank and immersed in the water therein for heating the latter. A

2. In an incubator a water tank, circulation pipes having connnunication therewith, said tank having an opening through its top, a vacuum heating element adapted to extend into the tank through said opening, and immersed in the water therein and a support for removably holding the said element in position.

3. In an incubator a water tank, circulation pipes ha ing communication therewith, said tank having an opening through its top, a cover for the tank, said cover embodying spaced elements, and a vacuum heating element supported by the cover to extend into the tank, said cover elements being held assembled by the said heating element. 4. In an incubator a water tank, circulation pipes having communication therewith, said tankghaving an opening through its top, a hollow cover for the tank, a vacuum heating element supported by the cover to extend into the tank, said element passing through one wall of the cover and engaging the opposite wall thereof, and vent openings leading through the wall of the cover outside of the tank.

5. In an incubator a water tank, circulation pipes having communication therewith,

said tank having an opening through its top, a cover for the tank, said cover comprising spaced elements, a socket connected with one of the elements, the other element having an opening therethrough in alinement with the socket, and an electric lamp passing through the opening in one cover element and engaging the socket on the other cover element to draw the cover elements together, said lamp projecting from the cover and extending into the tank.

(S. In an incubator a water tank, circulation pipes having communication therewith, said tank having an opening through its top, a cover for the tank, said cover comprising spaced elements, a socket connected with one of the elements, the other element having an opening thercthrough in alinement with the socket, an electric lamp passing through the opening in one cover element andengaging the socket on the other coverelement to draw the cover elements together, said lamp projecting from the cover and extending into the tank, and vent openings leading from the space between the cover elements.

7 In an incubator a water tank, circulation pipes having communication therewith,

]ecting from the cover and extending into I the tank, a lamp circuit and thermostatic means for controlling the lamp circuit.

8. In an incubator, a water tank, circulation pipes communicating therewith, said tank having an open top, a cover for the top frictionally held in position, an electric lamp arranged perpendicular to the cover to extend into the tank to heat the water therein, a lamp circuit, thermostatic means for'rontrolling the circuit, and a vapor outlet leading from the tank through the cover and to the outside 01"? the incubator.

In testimony whereof I have signed my name tothis specification, in the presence of two subscribing witnesses, on this 27th day of March A. D. 1915.
